Tobacco pipe



Patented Oct. 28, 1947 Application February 15, 1945, Serial N o. 577,994

- In Great Britain June 16, 1943 This invention relates to tobacco pipes or cigar holders or cigarette or like holders and. hasfor its object to provide improvements therein.

It haspreviously been'proposed to provide a tobacco pipe having atobacco bowl of metal supported almost whollyin the atmosphere so as to be air cooled and connected to a metal condenser bowl or chamber beneathit by awasher of heat insulating material.

In accordance with the present invention I provide a tobacco pipe comprising a tobacco bowl of metal supported almost wholly in the atmosphere in such a. manner that it is air cooled and connected to a metal condenser bowl or chamberbeneath it by a ring of heat insulating material, the pipe or holder being provided with an intermediate bowl of heat insulating material for the purpose of intercepting heavy matter and directing the fumes across the surface of the condenser bowl.

It will be seen from the foregoing that the outside surfaces of the pipe maybe shaped in many ways to prevent distortion or gain efiiciency and at the same time not appreciably lose any of the radiating or air cooling effect.

An orifice or orifices from the'bottom of the tobacco or radiator bowl deliver the fumes to the intermediate bowl and orifices in the upper part of the intermediate bowl direct the fumes so that they are spread across the fullest possible area of the condenser bowl, from which the fumes are drawn in a cool dry state through a stem orifice joined into or integral with the condenser.

The tobacco bowl, the ring member and the condenser may be a push fit with each other and so held together, or any common mechanical method may be used such as screwing or wedging,

so long as the metal condenser is kept away from the tobacco bowl and the latter is raised almost wholly into the atmosphere.

The invention may be adapted for use with cigars, cigarettes, or cheroots by manufacturing in miniature forms and/or by making the three bowls coaxial with the mouthpiece.

The accompanying drawings illustrate the invention.

Fig. 1 is a sectional elevation of one form of pipe.

Fig. 2 is a sectional elevation showing a modified form of tobacco bowl inassembled relation with the intermediate bowl, the condenser bowl and its associated pipe stem being omitted.

Fig. 3 is a sectional elevation similar to Fig, 2

' showing another modified form of tobacco bowl.

Fig. 4 is a top plan view of Fig. 2.

1 Claim. (01. 131 197)" Referring to the drawing (Fig. l) I provide the pipe with a metal tobacco bowl a, with a metal condenser bowl I) and with a heat insulating bowl 0, intermediate to the tobacco bowl or radiator a and the condenser bowl I). These bowls being suitably spaced from each other.

The greater part of the axial length of the tobacco bowl 11 projects above the intermediate bowl 0 into the-atmosphere. The intermediate bowl 0 is made of heat insulating material preferably 'a plastic material similar to Bakelite, which will not absorb nicotine or moisture. Be-

tween the tobacco bowl a and the condenser bowl b there is disposed a ring member d of heat insulating, nonabsorbent material as above defined and this ring member d may be integral or mechanically connected with the intermediate bowl 0.

The intermediate bowl 0 is orificed at e and is provided for the purpose of intercepting heavy matter and of directing the tobacco fumes to a comparatively lengthy path across the condenser bowl 1;, orifices ,1 through the bottom of the tobacco bowl a allowing passage of the'fumes from the said bowl a to the intermediate bowl c; and the orifices e in the intermediate bowl are so distributed that they spread the fumes over a large an area as possible of the condenser bowl b. From the condenser bowl b the fumes are drawn through the stem orifice y, the stem it being of the usual type.

In order to obtain the desired freedom from distortion and without appreciable loss of cooling effect, the tobacco bowl shown in Fig. 1 is provided externally with a plurality of ribs or pro jections 70 forming annular channels extending entirely around the bowl so as to permit free circulation of air therearound.

In Fig. 2, wherein only the tobacco bowl and intermediate bowl are shown, the assemblage of tobacco bowl a ring (1 and intermediate bowl 0 is the same as that shown in Fig, 1'.

' ever, a jacket k in this instance is turned over from the body of the tobacco bowl, the jacket being vertically tapered so that at its lower end it is spaced some distance away from the tobacco bowl, as shown at n, openings 0 (Figs. 2 and 4) being formed at the top of the jacket where it is turned over from the tobacco bowl, so that air may flow freely between thejacket and tobacco bowl.

In Fig. 3, the construction of the tobacco bowl a and jacket as a unitary structure is the same as shown in Fig. 2. In Fig. 3, however, the tobacco bowl is provided with'a removable lid 1' which Howwould more or less close the openings formed at the juncture of the tobacco bowl and jacket, for which reason the tobacco bowl is provided near its upper end with lateral openings m communicating with the annular space Z formed between the bowl and the jacket so that free circulation of air between the jacket and bowl is provided for just as in Fig. 2. The orifices in the intermediate bowl may be merely circular openings as shown at e in Figs. 2 and 3, instead of the elongated openings e shown in Fig. 1.

While the condenser bowl, ring member carrying the intermediate bowl and tobacco bowl are shown herein as screw connected together, it will be readily understood that if preferred, these members may be connected by slip joints,

I thus provide a multiple chamber smokers pipe in which the fumes, after leaving the tobacco bowl or radiator, do not become reheated by con tact with the side walls of the tobacco bowl.

What I claim and desire to secure by Letters Patentis:

A tobacco pipe, comprising a condenser bowl provided with a tubular stem in communication therewith, .a tobacco bowl disposed above said condenser bowl in .spaced relation thereto, a ring of heat-insulating material disposed between the tobacco bowl and the condenser bowl and operative to connect said bowls together, an intermediate bowl integral with said ring and disposed between the tobacco bowl and the condenser bowl in spaced relation to both of said bowls, and a jacket integral with said tobacco bowl and disposed around said bowl in spaced relation thereto, said tobacco bowl and intermediate bowl having orifices establishing intercommunication between said bowl and the condenser, the orifices in the intermediate bowl being disposed so as to spread the fumes from the tobacco bowl over the maximum area of the condenser bowl, the organization being such that the tobacco bowl is supported almost entirely in the atmosphere?
